Under-floor heating pipe

Description

Floor heating systems made of heating pipes of polybutene (PB), polypropylene (PP) or cross-linked polyethylene (PEX) can cause potential corrosion of the metal parts in the heating element due to the oxygen that easily permeates through the plastic pipes and into the heating circuit. To avoid this corrosion several options can be taken: using corrosion resistant material adding rust-preventive agents into the water reducing the oxygen permeability of the pipe. Reducing the oxygen permeability of the pipes is the most secure and economical solution. By using a multilayer pipe made of plastic containing an EVALâ„¢ barrier layer, the oxygen transmission rate will be reduced to a minimum and the corrosion of the metal parts in the heating system is minimised. The gas barrier property of the EVALâ„¢ resins prevents oxygen from permeating through the wall of the pipe and subsequently dissolving into the circulating hot water, thereby corroding metal parts in the heating element.
